Takafumi Takaoka possesses brown hair and brown eyes, typically accented by light-blue square-rimmed glasses. His signature attire is a red sweater with red sleeves and shoulders framing a white center panel. As nephew to Yousuke Shibazaki (called Uncle), who awakened from a 17-year coma after returning from the fantasy realm Gran Bahamal, Takafumi assumed guardianship when other relatives declined responsibility. Though initially reluctant, he embraced this role after witnessing Uncle’s genuine magic, committing to help him reintegrate into modern society. Takafumi’s childhood was marked by family instability: his parents divorced amid stress over Uncle’s medical condition, and he endured bullying from childhood friend Sumika Fujimiya—a memory he paradoxically cherishes. Financial strain forced him to skip college and rely on part-time work, fostering an escapist inclination toward light novels and otherworldly fantasies. Pragmatic and organized, Takafumi manages household logistics and launched a YouTube channel monetizing Uncle’s magic through ad revenue. He devises practical applications for these powers, like reducing shipping costs via flight spells. While often the grounded counterpart to Uncle’s eccentricity, he occasionally reveals dramatic enthusiasm for magical phenomena. His relationships remain complex: he shares a home with Uncle, developing genuine care for him despite early reservations. Sumika Fujimiya now harbors romantic feelings for him, though Takafumi remains oblivious despite easily recognizing others' romantic cues. He sometimes checks her photos for rival suitors, hinting at unacknowledged possessiveness. Ties to other family members stay strained due to disputes over Uncle’s guardianship. Takafumi cannot innately wield magic without spiritual contracts. In Chapter 35, he gained transformation magic after the Spirit of Form deemed his spirit "noble" for refusing to misuse a transformed female body. He later innovated shortened incantations for faster spells, effective despite perceived rudeness toward spirits. His strategic mind complements Uncle’s powers, though occasional overambition causes complications. Key details include his age progression from 19 to 20 during the story, coinciding with Uncle turning 35—indicating Takafumi was born when Uncle was roughly 14 or 15. He knows 1990s pop culture, including SEGA’s discontinued console production, which deeply distresses Uncle.
